After reviewing and physically interpreting the 2nd order GBT equations, a brief description of the main steps involved in performing a member GBT linear stability analysis is presented. Next, the paper addresses the issue of whether the critical stress value obtained from a member linear stability analysis corresponds to a “true bifurcation” or simply provides an “asymptotic limit load” and, in particular, a systematic procedure to detect true bifurcations is proposed. Finally, the application and capabilities of the 2nd order GBT are illustrated, by means of an investigation of the local and global buckling behavior of lipped channel columns and beams exhibiting asymmetric orthotropy.
